Hydroclimatic risks and adaptive capacity are not distributed evenly in large river basins of federal countries, where authority is divided across national and territorial governments. Transboundary river basins are a major test of federal systems of governance because key management roles exist at all levels. This paper examines the evolution and design of interstate water allocation instituti...
This paper describes an integrated mathematical model, OPER, for use in the analysis and planning of multipurpose water resources systems. A typical system consists of reservoirs, hydropower stations, irrigated land, artificial and navigation channels, etc., over a reach of a river or a river basin. The model takes into account the hydrological, technical, sociopolitical and economic constraint...
Floods are one of the most abundant and destructive natural disasters that every year are caused heavy losses of life and property. Due to human activity in river systems and construction in rivers, flood damage has an upward trend. One of the most important actions to reduce flood damage is the provision of flood hazard zoning maps and their use in spatial planning. In this study, the risk of ...
this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...
A planning model for a river basin development is constructed and applied to the Russian River Basin in California. Using dynamic programming methods, the problem is set in both deterministic and stochastic frameworks. In the latter, future population in the region and the corresponding time-dependent, price-sensitive demand relationships for water are projected with stochastic disturbance. A l...
A linear-programming model for use in analysis and planning of multiobjective water resources systems is described in this paper. A typical system consists of reservoirs, hydropower stations, irrigated land, artificial and navigation channels, etc., over a reach of a river or a river basin. The linear programming approach is studied and compared with other approaches: mixed integer-linear dynam...
The Sinos River Basin is often mentioned as a highly degraded watershed. A series of impacts on water quality, soil and air has been reported in this environment on a recurring basis over the years. This situation of environmental degradation has its origins in a process of huge economic development uncoupled from environmental conservation concerns. The intense consequent urbanization observed...
Rapid urbanization changes the land use/land cover pattern of a developing region. Due to these land surface changes, stream flow of the rivers also changes. It is important to investigate the factors affecting hydrological characteristics of the river basin for better river basin management planning. This study is aimed to understand the effect of Land Use/Land Cover (LU/LC) changes on stream ...
Information is provided about the approach and experience in flood management in the Damodar river basin of India. This is achieved through a scheme for the integrated operation of a number of reservoirs on that river and on its tributaries for the purpose of irrigation, hydropower generation and flood protection. Of particular interest is the recent change in policy towards a multi-disciplinar...
The deteriorating water quality of the Danube River and the ecological problems created by its continuing exploitation for electricity generation are major issues facing countries in the Danube River Basin. In response, representatives from the eight Danube riparian countries have recently declared their willingness to cooperate on the management of this important European river. In the absence...
