Lakes have long been recognized as being rich storehouses of environmental information. A lake basin collects water, but also sediment, much of which has been weathered and transported via fluvial processes from the near and far reaches of its drainage basin. The amount of water held in a lake is recorded on the landscape in coastal erosional and depositional landforms created at the water’s ed...

A key component of a sediment yield prediction is an estimate of the sediment deposition between erosion sources and a drainage basin outlet. This technical note presents methods requiring a minimum of data which can be used to assess the importance of sediment deposition within the river system of a basin. The methods were applied to a 4123 km basin in the Philippines. Results indicated that s...

This paper describes TerraHidro that is a distributed hydrologic modeling platform. TerraHidro is general purpose water resources system that presents a new concept to represent water flows based on graph structure, in the geographic information system (GIS) context. The drainage extractions and Amazonian basin delimitations using TerraHidro have been compared with ArcGis Hydro Tools regarding ...

Despite the arid to hyperarid climate of the Great Sahara of North Africa, pluvial climates dominated the region. Radar data shed some light on the postulated Trans-African Drainage System and its relationship to active and inactive tributaries of the Nile basin. Interpretations of recent elevation data confirm a source of the river water from the Red Sea highlands did not connect the Atlantic ...

Fractal dimensions have been frequently applied to generalize the complexity and drainage of particular stream networks. Certain techniques to calculate dimension have become particularly popular, specifically the Divider method, functional-box counting, and as a function between bifurcation and length ratios. The frequency and variability with which these techniques are applied creates discrep...

This paper aims to present terrain characteristics of Kuya river basin specially relief zoning, aspect analysis, hill shade view, its relation with drainage conditions etc. Analysis of SRTM data in ERDAS Imagine and Arc GIS software reveals that there is no siginificant relief difference between upper and lower catchment of the basin but distinction between upper and lower catchments is very cl...

OBJECTIVES To assess whether an association exists between drainage to multiple basins and lymphatic metastasis in patients with truncal melanoma. METHODS We retrospectively reviewed 227 patients with primary malignant melanoma between January 2006 and December 2009. All patients received an intradermal injection of (99m)Tc-nanocolloid and lymphoscintigraphy followed by sentinel node biopsy. ...

This paper introduces the Soil and Water Assessment Tool (SWAT) as a tool of decision makings for the Integrated Lake Basin Management (ILBM). I show how the analytical framework is applied to one of drainage watersheds in Laguna de Bay in Philippines toward sustainable lake basin management through the ILBM-Governance project.

This work presents the necessary steps to obtain the quantitative parameters of a superficial drainage basin, using digital image processing techniques such as segmentation and mathematical morphology.

In this retrospective cohort study of 280 primary total knee arthroplasties, clinical outcomes relevant to hemostasis were compared by electrocautery type: traditional electrocautery (TE), bipolar sealer (BS), and argon beam coagulation (ABC). Age, sex, and preoperative diagnosis were not significantly different among the TE, BS, and ABC cohorts. The 3 hemostasis systems were statistically equi...
