The Analysis of River Basins and Channel Networks Using Digital Terrain Data
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, , Massachusetts Institute of Technology, Dept. of Civil Engineering, 1989-09)This work examines patterns of regularity and scale in landform and channel networks. Digital elevation model data sets from throughout the United States are used as a data source. First we consider the two-dimensional ... -
Landsurface Hydrology Parameterization for Atmospheric General Circulation Models: Inclusion of Subgrid Scale Spatial Variability and Screening with a Simple Climate Model
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, Massachusetts Institute of Technology, Dept. of Civil Engineering, 1989-09)Parameterizations are developed for the representation of subgrid hydrologic processes in atmospheric general circulation models. Reasonable a priori probability density functions of the spatial variability of soil moisture ... -
Physically-based Parameterization of Spatially Variable Soil and Vegetation Using Satellite Multispectral Data
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, Massachusetts Institute of Technology, Dept. of Civil Engineering, 1989-09)A stochastic-geometric landsurface reflectance model is formulated and tested for the parameterization of spatially variable vegetation and soil at subpixel scales using satellite multispectral images without ground truth. ...
