Snow Cover Mapping using Microcomputer Image Processing Systems
Snow Cover Microcomputer Image Processing Systems
2009/10/26
For many years, digital snow cover mapping using satellite data had to be
carried out on large and expensive image processing systems. Recently, small
computer systems (microcomputers) have been dev...
Hydrology of a Patterned Bog-Fen Complex in Southeastern Labrador,Canada
Patterned Bog-Fen Complex Southeastern Labrador
2009/10/26
A 0.05 km2 patterned bog and a 0.29 km2 ribbed fen were compared to determine
the influence of their morphometry on runoff and evapotranspiration.
The bog hydrology was dominated by irregularly loca...

2009/10/13
We present an improvement of Clark's Instantaneous Unit Hydrograph (IUH), which we call the "GAIUH", linking hydrological parameters and geomorphologic characteristics of flatland basins with strong h...
新疆铁干里克绿洲水文过程对土壤盐渍化的影响
绿洲 地下水埋深 土壤盐渍化 塔里木河
2009/9/16
在对塔里木河下游绿洲地表灌溉水和地下水水质特征及土壤盐分实测分析的基础上，探讨了地表水、地下水过程及其对土壤盐渍化的影响。结果显示：塔里木河下游绿洲灌区地表水矿化度与土壤表层0~50 cm盐分含量呈显著正相关，与50~100 cm土层含盐量相关性不显著；地下水埋深与土壤盐分含量密切相关，0~50 cm表层土壤盐分含量随地下水埋深的增加而下降，其中0~20 cm下降幅度最大。当地下水埋深较浅时，...
Pedo-transfer functions are largely used in soil hydraulic characterisation of large areas. The use of physico-empirical approaches for the derivation of soil hydraulic parameters from disturbed sam...

Mapping an index of extreme rainfall across the UK
rainfall digital terrain model maximum rainfall
2009/6/5
Distance from the sea, proximity of mountains, continentality and elevation are all useful covariates to assist the mapping of extreme rainfalls. Regression models linking these and other variables ca...
The geomorphological unit hydrograph – a critical review
geomorphological unit hydrograph instantaneous unit hydrograph
2009/5/27
The theory of the geomorphological unit hydrograph (GUH) is examined critically and it is shown that the inherent assumption that the operation of the drainage network may be modelled by a correspondi...
