Impact of physico‐geographical factors and climate variability on flow intermittency in the rivers of water surplus zone

Many people in Indonesia calculate design rainfall before calculating the design flooddischarge. The design rainfall with a certain return period will eventually be convertedinto a design flood discharge by combining it with the characteristics of the watershed.However, the lack of a network of rainfall recording stations makes many areas that arenot hydrologically measured (ungauged basin), so it is quite difficult to know thecharacteristics of rain in the area concerned. This study aims to analyze thecharacteristics of design rainfall in Lampung Province. The focus of the analysis is toinvestigate whether geographical factors influence the design rainfall that occurs in theparticular area. The data used in this study is daily rainfall data from 15 rainfallrecording stations spread in Lampung Province. The method of frequency analysis usedin this study is the Gumbel method. The research shows that the geographical location ofan area does not have significant effect on extreme rainfall events. The effect of risingearth temperatures due to natural exploitation by humans tends to be stronger as a causeof extreme events such as extreme rainfall.Keywords: Influence, geographical, factors, extreme, rainfall.

Artikel ini bertujuan menganalisis kondisi sosial-ekonomi masyarakat Tatar Sunda pada abad ke-5 hingga abad ke-16. Metode yang digunakan adalah metode sejarah yang meliputi empat tahapan kerja, yaitu heuristik, kritik, interpretasi, dan historiografi. Hasil dari kajian ini adalah bahwa wilayah Tatar Sunda memiliki potensi ekonomi yang sangat tinggi. Hal ini dimungkinkan berkat faktor-faktor geografis. Tatar Sunda memiliki tanah yang sangat subur dan bisa ditanami oleh beragam jenis tanaman, termasuk tanaman ekspor yang sangat laku di pasar internasional. Di samping itu, wilayah Tatar Sunda pun cukup strategis karena memiliki banyak pelabuhan yang bisa dijadikan akses ke luar dan masuknya barang dan orang dari dalam dan luar Tatar Sunda.This article aims to analyze the socio-economic conditions of the Tatar Sunda community in the 5th to the 16th century.The method used is a historical method that includes four stages of work, namely heuristics, criticism, interpretation, and historiography.The result of this study is that the Tatar Sunda region has very high economic potential.This is possible because of geographical factors. Tatar Sunda has very fertile land and can be planted by various types of plants, including export crops needed on the international market.In addition, the Tatar Sunda region is also quite strategic because it has many ports that could be used as access to the outside and the entry of goods and people from inside and outside the Tatar Sunda.

Palabras Clave

La variabilidad climática es la norma que ha modulado la vida en el planeta. Este trabajo demuestra que las pesquerías y acuicultura costera ecuatorianas no son la excepción, puesto que tales actividades están fuertemente influenciadas por la variabilidad ENSO (El Niño-Oscilación del Sur) y PDO (Oscilación Decadal del Pacífico), planteándose que la señal del cambio climático debe contribuir a esta influencia. Se destaca también que, en el análisis de los efectos de la variabilidad climática sobre los recursos pesqueros, el esfuerzo extractivo también debe ser considerado. Por su parte, la acción actual de la PDO está afectando la señal del cambio climático, encontrándose actualmente en fases opuestas. Se espera que estas señales entren en fase a finales de esta década, y principalmente durante la década de los 20 y consecuentemente se evidencien con mayor fuerza los efectos del Cambio Climático. Palabras Clave: Variabilidad Climática, Cambio Climático, ENSO, PDO, Pesquerías, Ecuador. ABSTRACT Climate variability is the standard that has modulated life in the planet. This work shows that the Ecuadorian fisheries and aquaculture are not the exception, since such activities are strongly influenced by ENSO variability (El Niño - Southern Oscillation) and PDO (Pacific Decadal Oscillation), considering that the signal of climate change should contribute to this influence. It also emphasizes that in the analysis of the effects of climate variability on the fishing resources, the extractive effort must also be considered. For its part, the current action of the PDO is affecting the signal of climate change, now found on opposite phases. It is hoped that these signals come into phase at the end of this decade, and especially during the decade of the 20’s and more strongly evidencing the effects of climate change.
