The variability of the second order moments of flood peaks with respect to geomorphoclimatic basin characteristics was investigated. In particular, the behaviour of the coefficient of variation (Cv) of the series of annual maximum floods was analysed with respect to its dependence on physically consistent quantities. The results achieved were in fairly good agreement with real world observed ch...

Many coastal basins of the Brittany peninsula (France) display a high level of nitrate pollution, nine of them highlighted by the European Commission since 2007, as causing algal blooms in several coastal bays. To precisely diagnose and solve this issue the fluxes of every contributing basin have to be considered. However, this faces a strong data-scarce situation as most of the basins are unga...

A P index was developed as a tool to rank agricultural fields on the basis of P loss vulnerability, helping to target remedial P management options within watersheds. We evaluated two approaches, a soil P threshold and components of a P index, by comparing site vulnerability estimates derived from these two approaches with measured runoff P losses in an agricultural watershed in Pennsylvania. R...

Soil loss (SL) and its related sedimentation in mountainous areas affect the lifetime functionality of dams. Darbandikhan Lake is one example a dam lake Zagros region that was filled late 1961. Since then, has received considerable amount sediments from upstream area basin. Interestingly, series dams have been constructed (13 dams), leading to change rate arriving at main reservoir. This motiva...

introduction rainfall erosivity, the propulsion or power of causing erosion in separation and transport of soil particles, is in relation to water erosion. rainfall erosion is causing loss of soil, damage to agriculture and infrastructures which is followed by water pollution. changes in rainfall patterns exacerbate risk of erosion globally. rainfall erosivity plays an effective role in soil er...

drought monitoring is a fundamental component of drought risk management. it is normally performed using various drought indices that are effectively continuous functions of rainfall and other hydrometeorological variables. in many instances, drought indices are used for monitoring purposes. geostatistical methods allow the interpolation of spatially referenced data and the prediction of values...

As in most part of Africa, the Bani basin (Niger River, Mali) is threatened by climate changes. This study focuses on droughts hazard and its indicators as derived from the Climatic Moisture Index using the monthly data for the period (1963-2000), in order to examine the Bani basin vulnerability to water stress. In this study, water deficit (drought) was logically addressed using the Standardiz...

Abstract. The use of satellite sensors to infer rainfall measurements has become a widely used practice in recent years, but their spatial resolution usually exceeds 10 km, due technological limitations. This poses an important constraint on its for applications such as water resource management, index insurance evaluation or hydrological models, which require more and detailed information. In ...
