Hydroxyethyl cellulose (HEC) is a water-soluble polymer derived from cellulose, known for its excellent thickening, binding, and film-forming properties. Its applications span various industries, including pharmaceuticals, food, cosmetics, and construction. One of the critical factors influencing its widespread use is the cost, commonly referred to as the price per kilogram.

Another important consideration is the scale of the event being modeled. For large-scale analyses, such as regional flood assessments, coarser cell sizes can suffice since they provide a general understanding of hydrologic behavior across broader areas. However, for localized flood events, such as those impacted by urban drainage systems or levee breaches, finer cell sizes become imperative to capture the intricacies of water movement and to minimize computational errors which may arise from oversimplifications.

Lastly, the choice of cell size can also affect the stability of numerical models. In some cases, particularly in highly dynamic environments where sudden changes occur (like flash floods), smaller cells could provide a more stable solution. However, excessively small cell sizes can lead to numerical instability and convergence issues, making it vital to find an optimal size that balances resolution and stability.

One of the key properties of MHEC is its thickening ability. When added to water, it increases the viscosity of the solution, making it an excellent thickening agent. Additionally, MHEC exhibits excellent stability, allowing it to maintain its thickening properties over a wide range of temperatures and pH levels. This stability is particularly beneficial in applications that require long-lasting performance.

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose.
