Cambridge Core - Environmental Science - Runoff Prediction in Ungauged Basins - edited by Günter Blöschl. Scarcity of measured hydrologic data is the main cause for difficulty in demonstrating the assessment of groundwater recharge. The aim of this study is to provide a new scope to assess the runoff and groundwater recharge in ungauged basins based on paleo-flood and morphometric features in arid environment in spite of limited hydrological : Milad H.

Model simulations of future climate scenarios suggest a warmer Greenland overall (Fettweis et al. ; Stendel et al. ; Mernild et al. a, b), and the associated accelerating runoff and calving could perturb the THC by reducing the ocean density contrasts that drive the circulation (Rahmstorf et al. ). Therefore, quantifying. Effects of land-use change on runoff response in the ungauged Ta-Chou basin, Taiwan Fig. 2 Supervised classification of images for (left) and (right). Runoff calculations The influence of observed land-use changes on runoff is examined using a distributed rainfall-runoff model and design hyetographs with various return periods. Such an event may affect runoff generation and the frequency characteristics of events that follow it, particularly in small basins. All these complicating factors affect our ability to predict the response of an ungauged basin using physically based models, one of the ultimate tests of physical hydrology. Long-term hydrologic prediction in ungauged basins is one of critical issues in the field of hydrologic calculations. Hydrologic analogy is an important method for long-term hydrologic prediction and hydrologic calculation in ungauged basins. The key point of hydrologic analogy is how to select a reference basin.
At present, physically based glacier runoff models are simple representations of a complex natural system (e.g., Hock and Jansson ). But, with the HydroFlow routines for estimating drainage area, watershed divides, the flow-accumulation network, the time evolution and spatial distribution of different water transport mechanisms, and the. The use of physical basin properties and runoff southern Africa have been based on the original Pitman monthly rainfall–runoff model (Pitman, ) or recent revisions (Hughes, ). It is a conceptual type model and threshold for soil moisture runoff to occur. Simple . Recent measurements by the Geological Survey of Greenland (GGU) confirm a relation between glacier ablation and air temperature expressed in the form of positive temperature sums. The relation has already been used for the simulation of runoff from glacier-covered basins but might also be suitable for calculating ablation under alternative. Current models may underestimate runoff from the Greenland ice sheet by several tenths because they use a degree-day factor for melting ice that is too small for the colder parts of the ice sheet.
