Collaborative Modeling

Water resource management for most Southwestern states requires collaborative solutions that cross regional, state, and federal judicial boundaries. As most of the region experiences drought-like conditions as well as population growth, there is a growing concern about sustainability of the water resource to meet industrial, agricultural, and residential demands. Technically, seeking a consensus path requires modeling of the hydrologic cycle within a prescribed region. Credible models must capture key interdependencies of various water resources, use historical data for calibration, and provide temporal/spatial resolutions that are aligned with the interests of the decision makers.

Natural and human-caused climate changes are strongly linked to the hydrologic cycle and freshwater resources. The hydrological cycle is a core part of climate dynamics involving all three common forms of water—ice, liquid, vapor—and the movement of water around the world. Changes in climate affect all aspects of the hydrologic cycle itself through alterations in temperature, precipitation patterns, storm frequency and intensity, snow and ice dynamics, the stocks and flows of water on land, and connections between sea levels and coastal wetlands and ecosystems. In addition, many of the social, economic, and political impacts of climate change are expected to be felt through changes in natural water resources and developed water systems and infrastructure. Extensive research extending back a century or more has been conducted around the world on all the subsection categories presented below. Despite many remaining uncertainties, major advances in basic scientific understanding of the complex processes surrounding freshwater and climate have been made in the past decadet. New ground- and space-based sensors collect far more water- and climate-related data in the 21st century than in the past. Improvements in both regional and global hydrological and climatological modeling have permitted far greater understanding of water and climate links and risks. And more water management institutions and managers are beginning to integrate information about past and future climatic variability into water system planning, design, and construction. Recent observational evidence indicates that the impacts of human-caused climatic changes can now be observed in some regions for a wide range of water resources, including changing evaporative demand associated with rising temperatures, dramatic changes in snow and ice, alterations in precipitation patterns and storm, rising sea levels, and effects on aquatic ecosystems.

Modern portfolio theory developed for financial markets has application to water resource portfolios. It can help make decisions on how to optimally meet future water needs. By explicitly considering volatility and correlations among water resource alternatives, rational resource combinations can be selected. It enables water planners to decide how much to invest in traditional ways to meet water needs such as surface and groundwater supplies and to decide how much to invest in non-traditional, more expensive supplies such as recycling, conservation, and desalination. It enables explicit risk reduction of systematic risks due to the hydrologic cycle such as drought, and non-systematic risks such as water quality, climate, and energy. This paper describes a qualitative application of modern portfolio theory to water resources. Quantitative application will require the development of additional data.

Surface And Groundwater

This article discusses the joint modeling of surface and groundwater flows by presenting and describing the MC model. The purpose of this deterministic physically based model is to simulate the behavior of available water resources for one or many watersheds. The model integrates surface flow, streamflow, flow in the non-saturated zone, groundwater flow and the interactions between rivers and water tables. Its formulation and its structure, especially its nested square meshes of variable sizes, confer a great deal of flexibility to the model; this facilitates adaptation to variable modeling scales and to a wide range of geological, geographical and climatological conditions.

Italian Coast

The population density on the Italian coasts is twice the national average. Numerous urban, economic, and productive settlements lie along the coast, which in many areas have altered the natural characteristics of the territory. Moreover, recent climate change studies forecast large impacts on the hydrologic cycle in the Mediterranean. Thus, in the next years, coastal water resources will be gradually more stressed. This in turn may result in a progressive salinization, which is a widespread and worrying phenomenon worldwide. In this paper, the historical and geographical distribution of peer-review studies focusing on the salinization of water resources along the Italian coasts will be critically discussed.

Abstract The amount of eco-water resources reflects the land surface water conservation capability, and the underlying surface condition in the hydrologic cycle. In the upper Minjiang River Basin, the amounts of eco-water resources were retrieved from remotely sensed data during 1992 to 2005. Through regression analysis between the retrieved eco-water data and the climate hydrological data mainly including the temperature, the precipitation, and the runoff in the same period, the model of eco-water driving force affecting the evolvement of runoff was established. The accuracy analysis indicates that the model can well describe the relationship between dry season runoff and its driven factors, the measured data validation proves that the model has high precision and good practicability. The eco-water remote sensing inversion provides a valid method to quantify the land surface water conservation capability, and suggests an interesting approach for the driving function quantitative researches of underlying surface factor in the hydrologic cycle.
