Water Scarce

Hotels are a fundamental component within the tourist Spanish sector, and their role in water management turns out even more relevant taking into account the fact that tourist areas, in which they are generally located, are water scarce. Trying to go further from the standard ratios and estimations to plan water conservation, this work intends to really measure and quantify water use in rooms. Only by doing this, can subsequent conservation actions, now able to be reliably specified for each specific use, achieve a real success.

Abstract This study aims to investigate existing water management problems and potential solutions in the Al-Mafraq Governorate of Jordan, and to examine public awareness of water demand management at the household level. A questionnaire survey captured residents' perceptions of water quantity and quality. Results showed that 71% of respondents find the water pumped from the public system to be insufficient, and 40.9% find that water laws and regulations are implemented ineffectively. The study also showed that 85% of respondents are dependent upon groundwater wells, and 42.5% of respondents have suffered water contamination. Water quality is degraded due to pollution caused by solid waste and liquids, and salinity is increased due to the over-pumping and depletion of groundwater resources. The study recommends that the government incentivize residents to harvest water to deal with water shortages, religious motivations be explored in water conservation efforts, and water authorities should repair or replace old pipelines.

Abstract The relationship between water abstraction and water availability has turned into a major stress factor in the urban exploitation of water resources. The situation is expected to be sharpened in the future due to the intensity of extreme meteorological phenomena, and socio-economic changes affecting water demand. In the city of Volos, Greece, the number of water counters has been tripled during the last four decades. This study attempts to simulate the city's network, supply system and water demand through a forecasting model. The forecast was examined under several situations, based on climate change and socio-economic observations of the city, using meteorological, water pricing, users' income, level of education, family members, floor and residence size variables. The most interesting outputs are: (a) the impact of each variable in the water consumption and (b) water balance under four management scenarios, indicating the future water management conditions of the broader area, including demand and supply management. The results proved that rational water management can lead to remarkable water conservation. The simulation of real scenarios and future situations in the city's water demand and balance, is the innovative element of the study, making it capable of supporting the local water utility.

Danjiangkou Reservoir and its upstream tributaries as water resource area is of strategic importance for the Mid-route of South-to-North Water Transfer Project. Water conservation and water purification is the key measures for sustainable water diversion. Green water management as a new technologies to achieve water conservation and water purification has a broad application prospects. In this research, green water management was studied in the Upper Du watershed. ArcSWAT model was used to assess quantity of green water resource. By adjusting the model parameters, the efficiency of different green water management scenarios on water and soil conservation were simulated. The results of the study indicate that the quantity of green water in the Upper Du is about 5.588 billion cubic meters. Mulching is a better green water management way that more suitable for water and soil conservation in the Danjiangkou Water Resource Area. This research can provide a reference for water resource protection and management in Water Resource Area of the Mid-route of South-to-North Water Transfer.

Southern California’s Imperial Valley (IV) faces serious water management concerns due to its semi-arid environment, water-intensive crops and limited water supply. Accurate and reliable irrigation system performance and water productivity information is required in order to assess and improve the current water management strategies. This study evaluates the spatially distributed irrigation equity, adequacy and crop water productivity (CWP) for two water-intensive crops, alfalfa and sugar beet, using remotely sensed data and a geographical information system for the 2018/2019 crop growing season. The actual crop evapotranspiration (ETa) was mapped in Google Earth Engine Evapotranspiration Flux, using the linear interpolation method in R version 4.0.2. The approx() function in the base R was used to produce daily ETa maps, and then totaled to compute the ETa for the whole season. The equity and adequacy were determined according to the ETa’s coefficient of variation (CV) and relative evapotranspiration (RET), respectively. The crop classification was performed using a machine learning approach (a random forest algorithm). The CWP was computed as a ratio of the crop yield to the crop water use, employing yield disaggregation to map the crop yield, using county-level production statistics data and normalized difference vegetation index (NDVI) images. The relative errors (RE) of the ETa compared to the reported literature values were 7–27% for alfalfa and 0–3% for sugar beet. The average ETa variation was low; however, the spatial variation within the fields showed that 35% had a variability greater than 10%. The RET was high, indicating adequate irrigation; 31.5% of the alfalfa and 12% of the sugar beet fields clustered in the Valley’s central corner were consuming more water than their potential visibly. The CWP showed wide variation, with CVs of 32.92% for alfalfa and 25.4% for sugar beet, signifying a substantial scope for CWP enhancement. The correlation between the CWP, ETa and yield showed that reducing the ETa to approximately 1500 mm for alfalfa and 1200 mm for sugar beet would help boost the CWP without decreasing the yield, which is nearly equivalent to 44.52M cu. m (36,000 acre-ft) of water. The study’s results could help water managers to identify poorly performing fields where water conservation and management could be focused.

Scale Modelling

<p><span>In order to enable community groups and other interested parties to evaluate the effects of flood management, water conservation and other hydrological issues, better localised mapping is required.  Although some maps are publicly available many are behind paywalls, especially those with three dimensional features.  In this study London is used as a test case to evaluate, machine learning and rules-based approaches with opensource maps and LiDAR data to create more accurate representations (LOD2) of small-scale areas.  Machine learning is particularly well suited to the recognition of local repetitive features like building roofs and trees, while roads can be identified and mapped best using a faster rules-based approach. </span></p><p><span>In order to create a useful LOD2 representation, a user interface, processing rules manipulation and assumption editor have all been incorporated. Features like randomly assigning sub terrain features (basements) - using Monte-Carlo methods - and artificial sewage representation enable the user to grow these models from opensource data into useful model inputs. This project is aimed at local scale hydrological modelling, rainfall runoff analysis and other local planning applications. </span></p><p><span> </span></p><p><span>The goal is to provide turn-key data processing for small scale modelling, which should help advance the installation of SuDs and other water management solutions, as well as having broader uses. The method is designed to enable fast and accurate representations of small-scale features (1 hectare to 1km<sup>2</sup>), with larger scale applications planned for future work.  This work forms part of the CAMELLIA project (Community Water Management for a Liveable London) and aims to provide useful tools for local scale modeller and possibly the larger scale industry/scientific user. </span></p>

Rate Of Success

Narratives and discourses on issues such as water management and other complex social–ecological systems respond partly to people's worldviews or social perspectives. Knowledge of these perspectives might help increase the rate of success of specific initiatives related to water conservation and could be an important tool to improve water governance. A study performed in the city of Salta, Argentina, revealed the existence of four social perspectives on issues related to water management. Perspectives were obtained with Q methodology by interviewing 29 local stakeholders. Participants sorted 68 statements organized around four themes (service provider; water rights; public participation; water availability) according to their degree of agreement or disagreement. The findings support our contention that there are clear links between social perspectives and the rate of success of some water policies implemented by the local water utility in the past 15 years, in particular the promotion and use of household water meters and awareness campaigns launched to reduce water consumption. We show that the limited success of these initiatives was partly due to ignorance or disregard of social perspectives on water management.
