On the Clark Unit Hydrograph Model of HEC-HMS

Periodica Polytechnica Civil Engineering, 2017
A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.

Compatibility of personal care thickening polymers in sulphate‐free surfactants

International Journal of Cosmetic Science, EarlyView.
Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘

Assessing the Risk of 100-year Freshwater Floods in the Lamprey River Watershed of New Hampshire Resulting from Changes in Climate and Land Use [PDF]

, 2013
What is the coastal resource issue the project sought to address? Both the magnitude and frequency of freshwater flooding is on the rise in seacoast NH and around much of New England.

Comparing HEC-HMS and HEC-RAS for Continuous, Rain-on-Grid, Urban Watershed Modeling

Hydrology
The application of two-dimensional (2D) hydrologic and hydraulic modeling tools is increasing for overland flow simulation, as they represent spatial changes in depth, velocity, and flow conditions more accurately.

Ensemble physically based semi-distributed models for the rainfall-runoff process modeling in the data-scarce Katar catchment, Ethiopia

Journal of Hydroinformatics, 2023
This study evaluates the performance of the soil and water assessment tool (SWAT), the hydrologiska byråns vattenbalansavdelning (HBV) and the hydrologic engineering center-hydrologic modeling system (HEC-HMS) for modeling rainfall-runoff in the data ...

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Literature Review of Catchment Models in Aotearoa New Zealand for Ecological and Social Climate Change Effects

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
Shifting climatic averages and extremes are affecting both environmental and anthropogenic communities. This is a growing concern, especially for social–ecological systems (SES) such as lakes and their catchments, which integrate ecological and societal subsystems.

Sediment Modelling of a Catchment to Determine Medium-Term Erosional Trends

Land, 2023
This study was part of a project designed to simulate the long-term landform equilibrium of a rehabilitated mine site. The project utilized event Fine Suspended Sediment (FSS) fluxes in a receiving stream following a rainfall event as an indicator of ...

RAINFALL-RUNOFF SIMULATION OF A SUB-CATCHMENT USING HEC-HMS

Platform : A Journal of Engineering, 2022
Hydrological data in the form of stream flow is very scarce in most developing countries. This affects the planning and management of urban watersheds. Therefore, it is necessary to estimate peak discharge from rainfall using hydrologic models based on some measurable watershed characteristics.
