GIS techniques for developing a habitat classification for rivers
Under the Resource Management Act (1991) water managers are required to promote the sustainable management of natural resources, which involves safeguarding the life supporting capacity of water and ecosystems. To help water managers give practical effect to the concept of life supporting capacity, the Ministry for the Environment (MfE) and a number of regional councils are working collaborativ...
متن کاملSinuous rivers.
The windings of rivers have long fascinated their human observers. For example, Aboriginal legend explains the sinuous pattern of the modern Finke River (Fig. 1) as the creation of the immense and powerful Rainbow Serpent as he emerged during the Dreamtime from deep waterholes. Recently in PNAS (1), a new theory for the general origin of such sinuous flow patterns was published, which follows f...
متن کاملDeveloping Rating Curves for Bedrock Step-Pool Rivers using Sparse Data
The objective of this study was to investigate the possibility of a generic rating curve with a small number of adjustable parameters for the restricted class of bedrock step-pool rivers. The motivation for this study arose from Utah Valley University’s long-term program of groundwater development in the Trans-Mexican Volcanic Belt, which requires hydrographs for bedrock step-pool rivers near r...
متن کاملDeveloping reference criteria for the ecological status of West African rivers
Awareness of sustainable management of water and its biological resources is rising in West Africa, but application of effective tools for biomonitoring and detecting habitats at risk in aquatic ecosystems is limited. In this study, we provide key environmental descriptors to characterize reference sites by applying the following "a priori criteria" (physical and chemical, hydro-morphological, ...
متن کاملDeveloping a deep drainage risk map for the Border Rivers area
Deep drainage (DD) is recognised as one of the main drivers for dryland and irrigated salinity. Review of the literature on risk and hazard highlights few Australian studies on assessing DD risk and the need to develop new methods for determining DD risk. This study developed a method to map DD risk for the Northern Murray Darling Basin Catchment of the Border Rivers. Deep drainage was predicte...
