The use of geographic information systems (GISs) and remote sensing to facilitate the estimation of runoff from watershed and agricultural fields has gained increasing attention in recent years. This is mainly due to the fact that rainfall-runoff models include both spatial and geomorphologic variations. The US Department of Agriculture, Natural Resources Conservation Service Curve Number (USDA...

The article presents an analysis of water monitoring organization in the Sumy region. reform resources management has placed main burden on implementation state policy and ensuring proper ecological condition basin at regional level management. European approach field pays attention to monitoring, which is integral part system environmental Ukraine. An principle region had been conducted. There...

This paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from Mighan playa aquifer. Cluster analysis classified samples into four clusters(A, B, C and D) according to their dominant chemical composition: cluster A (dominant comp...

Streamflow forecasting has an important role in water resource management (e.g. flood control, drought management, reservoir design, etc.). In this paper, the application of Adaptive Neuro Fuzzy Inference System (ANFIS) is used for long-term streamflow forecasting (monthly, seasonal) and moreover, cross-validation method (K-fold) is investigated to evaluate test-training data in the model.Then,...

A spatio-temporal linear dynamic model has been developed for patching short gaps in daily river runoff series. The model was cast in a state-space form in which the state variable was estimated using the Kalman smoother (RTS smoother). The EM algorithm was used to concurrently estimate both parameter and missing runoff values. Application of the model to daily runoff series in the Volta Basin ...

The study site is located in an environmentally protected area known as an "APA" in São Pedro and Analândia, State of São Paulo, southeastern Brazil, whose watercourses are under strong anthropogenic pressure. Two basins were studied (sub-basin of the Corumbataí River and basin of the Jacaré-pepira River) with the purpose of characterizing the ichthyofauna of various streams, comparing fish div...

watershed is regarded as a very complex system of natural, social, economic and ecological dimensions and like any similar systems, exploitation of its resources requires a comprehensive and coordinated planning and management. given the importance of watershed management projects for the development and management of natural resources, the enhancement of the efficiency of these activities is e...

In the present study, basin morphometry of Hirehalla Sub-basin Bagalkote District, Karnataka was carried out using remote sensing and geoinformatics techniques. Delineation calculation various morphometric parameters sub-basin done in GIS environment. The study categorized into– Linear, Aerial Relief aspects. Result obtained from analysis confirms highest order fifth showing sub-dendritic to de...
