An example of carrying out unit hydrograph convolution in order to get the full Hydrograph of a catchment for a given hyetograph is explained in steps. Matrix manipulation using Excel is used for this regard and a simple user defined... more
A B S T R A C T Erosion by water is a major problem in agricultural areas, especially in mountainous zones. In this context, the mass of detached soil clods is affected by surface runoff. In this paper, the utility of simulated data has... more
Reproducibility and repeatability of experiments are the fundamental prerequisites that allow researchers to validate results and share hydrological knowledge, experi- ence and expertise in the light of global water... more
In many parts of the world, microbial contamination of surface waters used for drinking, recreation, and shellfishery remains a pervasive risk to human health, especially in Less Economically Developed Countries (LEDC). However, the... more
The problems involved in the environmental management of Cooum River in Chennai, India, relate not merely to pollution and environmental degradation, but to a complex situation involving linkages between social, economic and physical... more
Human-induced changes in flows of water, nutrients, and sediments have impacts on marine ecosystems. Quantifying these changes to systematically allocate management actions is a priority for many areas worldwide. Modeling nutrient and... more
Spatial analysis is currently a popular research tool, particularly in studies that focus on soil properties, and it is important for a comprehensive presentation of results by means of spatial statistics techniques. Spatial... more
The purpose of this research is to define initial parameters of Khyargas Lake-Zavkhan River and its catchment area us- ing satellite images. The study has been done by two datasets: 1) Shuttle Radar Topography Mission (SRTM) at a hori-... more
... The DPSIR framework (Driving forces Pressure State Impact response) has been chosen as the overall conceptual framework of the DSS. ... Alternatives D P S I R Figure 1: DPSIR framework: (D) Driving force; (P) Pressure; (S)... more
The long-standing issue of hydrological predictions in ungauged basins has received increased attention due to the recent International Association of Hydrological Sciences (IAHS) decade on predictions in ungauged basins (PUB). Since the... more
The paper compares two independent approaches to estimate soil moisture at the regional scale over a 4625 km2 catchment (Liebenbergsvlei, South Africa). The first estimate is derived from a physically-based hydrological model (TOPKAPI).... more
The objective of this study is to construct a balanced chlorine budget for a small forested catchment, focusing on the interaction between chloride (Clinorg) and organic-matter-bound chlorine (Clorg). Data from the actual catchment are... more
Land use is a predominant threat to the ecological integrity of streams and rivers. Understanding land use-water quality interactions is essential for the development and prioritization of management strategies and, thus, the improvement... more
This paper introduces the project on 'Assessing the impact of land use change on hydrology by ensemble modeling (LUCHEM)'that aims at investigating the envelope of predictions on changes in hydrological fluxes due to land use... more
The coastal belt in the southwestern Bangladesh is facing a unique problem compared to other parts of the country because of the direct interaction of the saline surface water (SW) from the coastal rivers and nearby sea with the fresh... more
La existencia de amenazas naturales y la vulnerabilidad de la población, hace evidente la existencia y la intensificación del riesgo, lo que conduce a una alta probabilidad de ocurrencia de un evento catastrófico. En tal sentido, se tiene... more
