distribution of the genus chondrostoma in iran, which is mostly known from the caspian sea, tigris river, kor river and esfahan basins was mapped. the kura nase, chondrostoma cyri is reported from armenia, georgia and iran and it is found in the streams and rivers draining to the western coast of the caspian sea from the kuma river in the north southward to the kura and aras river basins in the...

Foreword The CRC for Catchment Hydrology S2 project 'Managing Disposal Basins for Salt Storage within Irrigation Areas' was based on the premise that disposal basins are 'a fact of life' in the Murray-Darling Basin. Consequently there is a need for guidelines to site, design and manage them to minimise environmental and other problems. However, more than 190 existing basins were built when ther...

Extended Abstract—The redband trout Oncorhynchus mykiss ssp. occurs in interior basins of the Pacific Northwest. Oregon’s Great Basin populations of redband trout persist in fragmented habitats that are a result of the area’s geologic history, more recent hydrologic cycles of flood and drought, and anthropogenic disturbance. Concern about the status of these fish prompted the development of a n...

[1] We compare morphologies of drainage basins on Mars and Earth in order to confine the formation process ofMartian valley networks. Basins on both planets are computationally extracted from digital topography. Integral-geometry methods are used to represent each basin by a circularity function that encapsulates its internal structure. The shape of such a function is an indicator of the style ...

A basic problem relating to the long-term water balance involves splitting precipitation P, into runoff R, and actual evapotranspiration E. Berger and Entekhabi (2001) showed that the evapotranspiration efficiency E/Ep (Ep denotes potential evapotranspiration) and the runoff ratio R/P, are related to physiographic basin features and regional climate information. Berger and Entekhabi (2001) esti...

While today’s general purpose manipulators contain six degrees of freedom, effective reduction in degrees of freedom occurs from singularity regions and from workspace obstacles. It is argued that the future general purpose manipulators will contain seven degrees of freedom, and that one particular kinematic design is superior to other possible 7 degree of freedom kinematic designs. Considerati...

State educational spending policies strongly impact the funding of local schools. While some US states have removed school spending authority from local residents, others continue to encourage local control. In this paper we explore the effects of changes in state educational spending policies on Tiebout sorting by examining the location choice of young and elderly households, both within and a...

Any elementary textbook on statistical mechanics will try to convince you that energy is everything w.r.t. phase separation. The goal of this thesis is to show otherwise.

The notion that effective environmental governance depends in part on achieving a reasonable fit between institutional arrangements and the features of ecosystems and their interconnections with users has been central to much thinking about social-ecological systems for more than a decade. Based on expert consultations this study proposes a set of six dimensions of fit for water governance regi...


 Most of Nepal's river basins have poor hydro- meteorological databases, with several being ungauged. Thus, hydrological parameters need to be estimated using different types computation methods. The primary goal this study is identify the most accurate method for calculating peak flood and long-term mean monthly flow among commonly used methods in Nepal. We compared calculated various fo...
