Ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. Landscape planning can play a role in mitigating the effects of human-related activities. One element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...

(Glover et al . , 1988a, 1988b) and 1988 (Schiarizza et a l . , 1989d, 1989b). and extends the mapping eastward to include the eastem part of the Shulaps Range, the Yalakom and Bridge River valleys and the adjacent Camelsfoot Range. In addition, several weeks were spent re-examining critical areas in the Tyaughton Creek area and traversing the area south of Gun Creek in an effort to mesh our ...

Mathematically a natural river system is a rooted directed tree where the orientations of the edges coincide with the directions of the streamflows. Assume that in some of the river valleys it is possible to build reservoirs the purpose of which will be to retain the flood, once a year, say. The problem is to find optimal reservoir capacities by minimizing total building cost eventually plus a ...

Although only recently recognized, hanging tributary valleys in non-glacial landscapes are not uncommon in tectonically active regions. Standard river incision models do not allow for the formation of fluvial hanging valleys; these disequilibrium landforms present an opportunity to advance our understanding of river incision processes. In this work, we demonstrate that thresholds apparent in se...

We explore the role of large impacts in creating the Martian valley networks. Recent dating shows that some large impact basins are contemporaneous with the valley networks. The mass deposited (and volatiles released) by impacts is large, and comparable with the mass from the Tharsis volcanic construct. Steam atmospheres formed after large impacts can produce more than 600 m of rainfall, follow...

Water table forecasting plays an important role in the management of groundwater resources in agricultural regions where there are drainage systems in river valleys. The results presented in this paper pertain to an area along the left bank of the Danube River, in the Province of Vojvodina, which is the northern part of Serbia. Two soft computing techniques were used in this research: an adapti...

Generating realistic-looking but interesting terrains quickly is a great challenge. We present RiverLand, an efficient system for terrain synthesis. RiverLand creates a realistic-looking terrain by first generating river networks over the land. Then, the terrain is created to be consistent with the river networks. In this way, the terrains created have a proper drainage basin, an important feat...
