The data presented in this article are related to the research article entitled "Options for the remediation of embankment dams using suitable types of alternative raw (Drochytka and Kociánová, 2017) [1]. This article describes the possibility of use the fly ash as an optimal alternative material that can reduces costs and improves the rheological properties of the grouts. The grout data set is made publicly available to enable critical or extended analyses.

Given the complexity of the behavior of mining tailings dams built by the technique of hydraulic embankments and the recurring dam ruptures globally, especially in Brazil, ensuring enhanced safety through advanced disposal techniques becomes crucial. While the co-disposal method has been extensively explored for various mineral substances, a notable gap exists in the literature concerning its application specifically to tailings and waste rock generated from phosphate mining operations. This study aims to identify the optimal ratio for a mining tailings and waste rock mixture and evaluate its mechanical behavior in comparison to individual materials.

Background: Embankment dams were built south of the Laizhou bay in China for controlling storm surge disasters, but they are not enough to replace coastal forests in protecting the land. This study was designed to evaluate the effects of embankment dams on natural forests dominated by and test whether the dam-shrub system is a preferable updated defense.
Methods: Coastal forests on two typical flats, one before and one behind embankment dams, were investigated using quadrats and lines.

Leakage is a high-incidence disease of embankment dams, and efficiently addressing this disease guarantees the safe operation of dams. Underwater leakage self-priming plugging technology is a new technology that utilizes the melting and solidifying characteristics of phase-change materials and the negative pressure in the leakage entry area to accurately plug the leakage. However, little is yet known about the underwater melting process of phase-change materials and how their characteristics influence the plugging effect.
